SPECIFICATION forming part of Letters Patent No. 794,670, dated July 11,1905.

Application filed November 20,1903- Serial No. 182,039-

To all whom, it may concern:

Be it known that I, ROBERT JOHN FOSTER, of the city of Montreal,Province of Quebec, Canada, have invented certain new and usefulImprovements in Linotype-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the same.

In linotype-machines of this type in universal use the carriage isusually made in two parts adjustable toward and from one another anddetachably connected together in any position (relatively to oneanother) to which they may be adjusted, one of such parts including inits constitutional elements a bar which overlaps the other part and thelatter part including in its constitutional elements the longdelivery-finger, and means whereby the bar is connected to such latterpart to cause the two parts to under certain conditions move in unisonand whereby the firstmentioned part is detachably connected in anyposition to which it may be adjusted from the other part; and it furtherrelates to the device for setting or adjusting the assemblybar toaccommodatea predetermined length of line.

The object of the invention is to prevent the breakage of either suchlong deliveryfinger or the means for carrying it or the connectiontherebetween when the long deliveryfinger trips on a line of type notproperly delivered or other obstructions and to facilitate theadjustment of such finger along the bar.

A further object of the invention is to enable an operator to adjust theassembly-bar with greater facility and minuteness to accommodate apredetermined length of line.

The invention may be said, broadly speaking, to consist of meansadjustably connecting the long delivery-finger to the part'with which itmoves, such means being adapted to be readily adjusted by manual actionand at the same time yieldingly retain the finger in the position towhich it may be adjusted; and it further consists of a device forsetting or adjusting the assembler-slide to accommodate a predeterminedlength of line, such device being adapted to coact with graduations uponthe assembler-slide, whereby a positive adjustment of the length of linemay be had,

which enables an operator to locate on the machine a degree equivalentto the length of line required and to move such device to the requiredpoint to enable the assembly-bar to accommodate a predetermined lengthof line.

The invention further consists of a device in conjunction with the meansfor adjusting the assembler-slide for varying the extent of adjustment.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings, forming a part of this specification, inwhich similar reference characters indicate the same parts, and wherein-Figure 1 is a view of a portion of the front of a linotype-machineprovided with my invention. Fig. 2 is a plan view of the delivery-carriages with my invention applied thereto. Fig. 3 is a transversevertical sectional view of a portion of the machine, taken on line A A,Fig. 1; and Fig. 4: is a transverse vertical sectional view of theassembler-slide and the adjustable stop carried thereby and to which myinvention is applied.

The magazine 6, the parts 0 and d of the delivery-carriage, andassembler-bar e are in the main of usual construction.

A ratchet-toothed bar 9 is pivoted at one end, as at h, to and is aconstitutionalpart of the part (Z of the carriage, the teeth 4. thereofbeing formed in the lower edge and disposed a pica pitch apart. The longdelivery-finger k has a rigid pawl Z secured thereto near the upper endthereof and in position to engage the teeth of and support suchratchet-bar in'a horizontal position. A coiled spring 0%, bearing uponthis ratchet-bar, has its opposite end connected by a binding-screw mina perforation in a block 0, secured by a screw 19 and dowel-pin (1 uponthe part 0 of the carriage. This construction provides a carriage onepart whereof has an elongation (the bar g) which overlaps the other partand the connection just described between the long delivery finger,(forming a portion of said other part) and this bar enables the formerto be moved longitudinally of the bar the full length thereof to itsfree end.

The adjustable stop .9 acts in conjunction with a rigid stop 6 todetermine the length of line,

as usual; but according to my invention I slot the assembler-slide, asat a, and form the adjustable stop with a key 0), adapted to fitslidably into such slot, while a retaining-plate w is provided and isformed with a key y, adapted to fit into the slot at the opposite sideof the assembler-slide. A retaining-screw 2 is threaded through theadjustable stop into the retaining plate, thereby securing the saidparts together and connecting the stop slidably to the assembler-slide.This adjustable stop is caused to automatically lock itself in anyposit-ion to which it may be adjusted along the assembler-slide byaseries of perforations 3 in the upper portion of the latter, and apinpawl 4:, provided with ahead 5 and a rigid collar 6, is located in aboring in the adjustable stop between the inner end thereof and suchrigid collar. An expansile helical spring 7 bears and yieldingly retainsthe end of this pin-pawl in the perforation with which it is caused toregister. These perforations are preferably disposed a pica apart, or ifthe ratchet-bar is otherwise graduated the perforations will be spacedaccordingly, it being necessary to have the graduations of theratchet-bar and assembler-slide correspond. At times it is desirable toadjust the adjustable stop a distance more or less than one pica or themultiple thereof or whatever graduation may be adopted, and to enablethis to be done I hinge an angular bar or bent piece 10, as at 12, tothe top of the adjustable stop and adapt it to either lie upon the topof the latter or to be swung to a position having its end hanging downover the side of the adjustable stop which comes in contact with therigid stop, thus enabling such bent bar to be interposed and reduce tothe extent of its thickness the distance the assembly-bar is moved. Thisauxiliary stop is preferably one-half em in thickness, although thethickness thereof may be varied according to requirements.

The scales 0' and r are intended to enable the operator to center orjustify the line to be cast, particularly when tabular matter is beingset.

A coiled spring 8 is connected at one end to one part of the carriageand at its opposite end to the other part of such carriage and thefunction thereof is to yieldingly lightly retain the parts of thecarriage with a tendency to come together, thus retaining the rigid pawlZ in the engagement with the particular tooth of the rack with which itengages.

The operation of my invention is as follows: When the carriage isreturning after a line has been delivered, and if the longdeliveryfinger should happen to catch upon the top of a delivered lineof type which owing to some defect in the action of the machine or othercause has not been lowered into alinement with the mold, it will rest incontact with the top of the type and allow the ratchet-bar to run fromit, thereby preventing the breakage which would occur if the bar andfinger were either temporarily or permanently rigidly connectedtogether. Before the end of the bar can reach the finger the machinewill be automatically stopped as usual, owing to the line of type nothaving been lowered into alinement with the mold.

The advantages attendant upon the use of my invention, besides obviatingthe danger of breakage, as above pointed out, are that the long delivery-finger can be adjusted to different positions Without other manualaction being required than to simply move it to the point in graduationsrepresenting the length of line required to be formed, while theadjustment of the adjustable stop under the guidance of graduationscorresponding to the graduations on the ratchet-bar enables a positiveadjustment of the length of line to be made with the least possible lossof time. A further advantage is that owing to the flat ratchet-barbearing upon the flat side of each of the carriage parts theunsteadiness heretofore experienced in the carriage is obviated, thusalso obviating the chance of any portion of the carriage or partscarried thereby tripping upon parts of the machine they have to pass.

What I claim is as follows:
